The launch of the next-generation Vectra (or Insignia, as it has become) has been a long time coming, and Vauxhall is making good and sure everyone notices now that its time has arrived. As part of an elaborate marketing scheme, the automaker crashed a UFO in Potters Fields Park in London, and there was even a fence, men in dark glasses that were evidently mute and copious amounts of smoke to set the scene. Just how this relates to a new motorcar? You’ve got us there.
